In a large bowl, whisk together the mayonnaise, greek yogurt, fresh lime juice, and lime zest until smooth and bright.
Add the cumin, chili powder, salt, and black pepper to the dressing. Stir until all the spices are fully incorporated.
Add the diced cooked chicken breast and toss until every piece is coated in the creamy lime dressing.
Fold in the diced mango, red bell pepper, red onion, and minced jalapeño. Mix gently so the mango pieces stay intact and don't get mushy.
The mango should be ripe but still slightly firm so it holds its shape and adds a nice contrast to the creamy chicken.
Sprinkle the chopped fresh cilantro over the top and fold it through the salad one final time.
Cover and refrigerate for 20 to 30 minutes to let the tropical flavors come together. Serve in lettuce cups, on toasted coconut bread, or scooped up with plantain chips for something extra special.
